Provisioning User Equipment Route Selection Policies with Service Assurance

1. A method comprising: updating, by a Policy Control Function (PCF), a policy of a User Equipment (UE); creating, by the PCF, a UE route selection policy (URSP) based on the updated UE policy; setting, by the PCF, a flag in the URSP, wherein setting the flag comprises setting the flag in the USRP to a first value, wherein the first value indicates to the UE that the URSP is applicable for new sessions and inapplicable for ongoing sessions, and wherein setting the flag to a second value indicates to the UE that the USRP is applicable to all sessions; and sending, to the UE, the URSP from the PCF, wherein the UE applies the URSP for new sessions.

2. The method of claim 1, further comprising receiving, by the PCF, a message indicating results of the UE applying the URSP.

3. The method of claim 1, wherein sending, to the UE, the URSP from the PCF comprises sending, to an Access and Management Function (AMF), the URSP from the PCF.

4. The method of claim 3, wherein sending, to the UE, the URSP from the PCF comprises sending, to the UE, the URSP from the AMF via a Radio Access Network (RAN).

5. The method of claim 1, wherein the URSP comprises a URSP rule, and wherein the UE applying the URSP for new sessions comprises applying the URSP rule for new sessions.

6. The method of claim 1, wherein the PCF updates the policy of the UE based on the UE moving from a Fourth Generation (4G) network to a Fifth Generation (5G) network.

7. The method of claim 1, wherein setting the flag in the URSP is based on the updated UE policy being non-compatible with ongoing sessions.

8. A system comprising: a memory storage; and a processing unit coupled to the memory storage, wherein the processing unit is operative to: update a policy of a User Equipment (UE); create a UE route selection policy (URSP) based on the updated UE policy; set a flag in in the URSP, wherein setting the flag comprises setting the flag in the USRP to a first value, wherein the first value indicates to the UE that the URSP is applicable for new sessions and inapplicable for ongoing sessions, and wherein setting the flag to a second value indicates to the UE that the USRP is applicable to all sessions; and send, to the UE, the URSP, wherein the UE applies the URSP for new sessions.

9. The system of claim 8, wherein the processing unit is further operable to receive a message indicating results of the UE applying the URSP.

10. The system of claim 8, wherein the processing unit being operative to send, to the UE, the URSP comprises the processing unit being operative to: send, to an Access and Management Function (AMF), the URSP; and send, to the UE, the URSP from the AMF via a Radio Access Network (RAN).

11. The system of claim 8, wherein the URSP comprises a URSP rule, and wherein the UE applying the URSP for new sessions comprises applying the URSP rule for new sessions.

12. The system of claim 8, wherein the processing unit being operative to update the policy of the UE comprises the processing unit being operative to update the policy of the UE based on the UE moving from a Fourth Generation (4G) network to a Fifth Generation (5G) network.

13. The system of claim 8, wherein the processing unit being operative to set the flag in the URSP comprises the processing unit being operative to set the flag in the URSP based on the updated UE policy being non-compatible with ongoing sessions.

14. A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising: updating, by a Policy Control Function (PCF), a policy of a User Equipment (UE); creating, by the PCF, a UE route selection policy (URSP) based on the updated UE policy; setting, by the PCF, a flag in in the URSP, wherein setting the flag comprises setting the flag in the USRP to a first value, wherein the first value indicates to the UE that the URSP is applicable for new sessions and inapplicable for ongoing sessions, and wherein setting the flag to a second value indicates to the UE that the USRP is applicable to all sessions; and sending, to the UE, the URSP from the PCF, wherein the UE applies the URSP for new sessions.

15. The non-transitory computer-readable medium of claim 14, further comprising receiving, by the PCF, a message indicating results of the UE applying the URSP.

16. The non-transitory computer-readable medium of claim 14, wherein sending, to the UE, the URSP from the PCF comprises sending, to an Access and Management Function (AMF), the URSP from the PCF.

17. The non-transitory computer-readable medium of claim 16, wherein sending, to the UE, the URSP from the PCF comprises sending, to the UE, the URSP from the AMF via a Radio Access Network (RAN).

18. The non-transitory computer-readable medium of claim 14, wherein the URSP comprises a URSP rule, and wherein the UE applying the URSP for new sessions comprises applying the URSP rule for new sessions.

19. The non-transitory computer-readable medium of claim 14, wherein the PCF updates the policy of the UE based on the UE moving from a Fourth Generation (4G) network to a Fifth Generation (5G) network.

20. The non-transitory computer-readable medium of claim 14, wherein setting the flag in the URSP is based on the updated UE policy being non-compatible with ongoing sessions.
